PAPER CONTAINER.

Application led lilly 31,

The present invention relates to paper containers, that is, tocontainers made of any suitable fibrous stock Whether paper orresembling paper, and may be in the form of a can with a cylindricalside Wall, or in any suitable polygonal or curved form, Wound or formedin any suitable Way. The paper stock may be single or multiple ply withor without incorporating a binder, and the container may be coated Withparaiiin or the like and may have a paper covering or advertising label.c p

The container has any suitable form of topand bottom closures,preferably sealing the container, and a removable cover adapted toprotect the contents from contamination and deterioration after one ofthe closures has been removed by the consumer. The cover mayfrictionally engage the .top por- 'tion of the container, or thecontainerand cover may have interlocking means such as complementalgrooves, or both of these arrangements may be provided to resist theremoval of the cover.

lVhether or not .the interlocking means are provided, the container mayhave a seat furnished, for example, by reducing the diameter of aportionA of the s'ide Wallto form a ledge and a neck so that theremovable cover seats on the ledge and frictio'nally engages the neck.Preferably the diameter of the neck is reduced to the extent that thecover forms a continuation of the side Wall of the container to producea smooth surface throughout suitable for an outside Wrapper serving as aseal for the removal cover. Furthermore, the top 'closure of thecontainer may consist of a cap and a bead, in which case the removablecover may be made to seat thereon for su port in addition to thatfurnished by the le ge. Where interlocking means 'are included to securethe cover, the bead serves also to reenforce the side wall of the coverto compensate for any weakness due to the formation therein of part ofthe interlocking means. In either case the bead acts to support the sideWallv of the container against lateral pressure. A

Irrespective of the form of top and bottom closures .for the container,and the form of removable cover and the means for secur ing'it, theinvention comprehends as another of its parts a removable cover which isconstructed and arranged to enga e the end portion of the container, andto orm with one of the cap.

of the closures an enclosed chamber which may, for example, be used tocarry advertising or other printed mattei'. Where the removable cover isused in conjunction with the top closureof the container, the latter maybe sealed,`and both the cover and Vclosure may include caps spaced to'formv the enclosed chamber. i y

In the specific embodiment of the invention hereinafter described, thecontainer has sealed top and bottom closures each comprising a cap and abead spaced from the cap to facilitate its formation exteriorily of thecontainer, as Well as to allow for interlocking means to secure the capagainst longitudinal displacement under pressure, and the removablecover is formed with a closure including a cap which, When the cover isin place, forms with the topclosure an enclosed chamber. u In thelaccompanying drawings illustrating the preferred embodiment of theinventionin application, as an example, to a cylindrical container ofsingle ply stock having sealed top and bottom closures, Fig. l is anelevation of the cover partly .1n section; Fig. 2.is a similar elevationof the container; Fig. 3 is an enlarged sectional n detail of the topclosure and portion of the container, showing the removable cover inposition; and Fig. 4 is an enlarged sectional detail of the bottomclosure and portion of the container.

The container has a cylindrical side wall 1 of single ply stock andsuitable surface finish, and top and bottom openin s sealed by closures2 and 3 respectively. T e upper end of the side Wall l is reduced indiameter forming a neck 4 and a ledge 5, the latter serving as a seatfor the removable cover 6 which is made to frictionally engage the neck.Y

The top closure 2, and also the bottom closure 3, consists of a cap 7having a Wall 8 and a bead 9, the bead being formed of folded portionsof the side Wall l of the container and the Wall 8 of the cap.

lThe cover 6 has' a side wall 10 and Iits upper end has a closurecomprising a cap 11, and a bead- 12 Which is formed of\folded portionsof the side wall l0 and the wall. 13

The removable cover is made to tightly lit .the neck 4 and, to increasethe fricticnal engagement therewith, the inside `diameter of the sidewall 10 is made approxi- 110 mately equal to the outside diameter of theneck 4. Even though the diameters be eXactly equal, the cover may beadjusted Without iiculty by reason of the curvature at 14 acting toguide the lower` peripheral edge of the cover while the latter is beingforced in engagement with .the neck.

Impressed in the side wall 10 of the removable cover is an inwardlydirected projection 15 which engages the complemental groove 16 formedin the neck 4 and interlocks therewith to supplement the action offriction in resisting the Vremoval of the cover. By directing inwardlythe interlocking grooves for securing the cover 7 the groove 16 servesboth for receiving the projection 15 in the wall of the cover, and alsoto furnish the inwardly extending projection forming part oftheinterlocking means for the cover.

When the removable cover is seated on the ledge 5 the cap 11 contactswith the upper bead 9 which is spaced from the cap 7 to facilitate itsformation exteriorly of the container, as well as to allow for theinclusion of interlocking means to secure the latter, and the cap formswith the top closure an enclosed chamber 17, for instance three-eighthsof an inch in height, which may be used to carry advertising or otherprinted matter, Moreover, the bead 9 serves to support the removablecover, and particularly the side wall 10 thereof, thus compensatingfor-any weakness due to the inwardly extending projection 15, andreenforcing the support furnished by the led e 5 a ainst pressuresexerted longitudinal y of t e container. Furthermore, it reenforces theside wall against lateral pressures.

A paper container constructed as described is particularly well suitedfor articles requiring a tightly covered container for theirpreservation after as well as before the container is opened.Irrespective of the nature of the contents, however, the removable coveris desirable for (protection against the ingress of moisture an foreignmatter and to prevent the egress of the contents after the seal has beenbroken by the consumer. When the contents of the container have beenpacked and sealed, the removable cover is placed in position on theneck, and, since the wall of the cover forms a continuation of the bodyportion of the side wall of the container, a suitable covering oradvertising label may be pasted on the outside surface to provide a sealfor the cover.

Reference is made to my copending application Serial No. 400,460, filedJulcy 31, 1920, claiming subject matter disclose but not claimed in thepresent case.

Having thus described myv invention, what I claim is:

1. In a paper container, a side wall, top and bottom closures therefor,a portion of said side wall being reduced in diameter to form a neck andaledge with the ledge located below the top closure, a removable coverhaving a wall constructed and arranged to frictionally engage said neck,the end of said wall seating on said ledge and forming a continuation ofthe body portion of the side wall of the container, and interlockingmeans for resisting the removal of said cover comprising complementalgrooves formed in said neck and in the wall of said cover.

2. In a paper container, a cylindrical side wall, top and bottomclosures therefor, a portion of said side wall being reduced in diameterbeyond the closure to form a neck and a ledge located below the closure,a removable cover having a cylindrical wall constructed and arranged tofrictionally engage said neck, the end of said wall seating on saidledge to form a continuation of the body portion of the side wall of thecontainer, and interlocking means for resisting the removal of saidcover comprising comp @mental grooves in said neck and in the wall ofthe cover.
